Aspen Fuel

[ginbottle]

Thanks to everyone for their help and advice. I decided to use the Aspen 4 stroke, mixed with 2 stroke oil, as that was what the Aspen company suggested. It has certainly reduced the smoke and starts well, but after running for about an hour, suddenly started making a harsh squealing noise! Nearly jumped out of my skin the first time and the dogs weren’t too happy either! Any ideas as to the cause of this, please?

suggests lack of lubicant or over heating somewhere,  if could be cream crackered
